lain or treated chemically or otherwise, is

lnjected into the said apparatus when saidgases are passing through the same, in order to arrest and precipitate the pungent matter carried by said gases. In such apparatus the exhaust gases have passed through a body of accumulated water, thereby producing back pressure, and the gases have passed downwards in the same direction as the jets of water.

The object of the present-invention is to produce a deodorizer 1n which the liquid may be used continuously, in-which the back pressure is so slight that it is inappreciable, and which is very efiective in use.

According to the present invention the apparatus is provided with an outlet at its bottom so arranged as to prevent any accumulation of liquid, said outlet leading'to a sump or-receiver which is provided with a strainer or filter and a return pipe, through which latter theliquid is exhausted by means of a pump and returned to the cooler or other tank, from which the liquid again passes to the deodorizer, such pump and cooler forming part of the usual, or part of a special, water circulating system. Further, We do not pass the exhaust gases in the same direction as the jets of liquid, but we pass them preferably at right angles thereto, and we place the inlet and outlet pipes for the gases in such a position that the gases do not pass through an accumulated body of liquid.

When the apparatus is used as a com bined deodorizer and silencer the aforesaid screens or baffles, in addition to precipitating the water and pungent matter, act to silence the noise from the exhaust of the And in order that the invention may be more clearly understood and readily water enters the chamber a.

carried into effect we will proceed aided by the accompanying drawings more fully to describe'the same.

Figure 1 is a side elevation of a deodorizer partly in section and Fig. 2 is an end elevation of the same. Fig. 1 is a section showing a slight modification. Fig. 3 is a side elevation of a modified form of deodorizer and Fig. 4 is a section on the line 44 of Fig. 3. Fig. 5 is a side elevation partly in section of a deodor izer showing another modification and Fig 6 is a section on the line 6-6 of Fig. 5. Fig. 7 is a central longitudinal section of a combined deodor izer and silencer. Fig. 8 is a central longitudinal section of a modified form of combined silencer and deodorizer and Fig. -9 is a section on the line 99 of Fig. 8 looking upwards. Fig. 10 is a central longitudinal section of a combined deodorizer and silencer and Fig. 11 is a section on the line 1111 of Fig. 10. Fig. 12 is a front elevation of one of the foraminated screens.

As shown in Figs. 1 and 2 a is the chamber, b is the inlet for the exhaust gases and c is the outlet for said gases after they have been purified or deodorized. d, d are perforations in the case a and e is areceptacle for receiving the .water from the supply pipef, forming part of a water circulating system. As shown this pi e f has two branches so as to distribute t e water more evenly in the receptacle e. At one end of said chamber an o ening is formed leading by means of the short pipe g to the sump or receiver h which has an aperture leading into the return pipe 1' forming part of a water circulating system. The sump or receiver it has a strainer or filter h to collect the oil and anyg'pun gent matter, said receiver h having "anoutlet pipe which is provided with a cock k;

In the construction shown at Figs. 3 and 4 the receptacle e for the water from the supply -pipe f is located within the case a and the erforations d, d are formed in this receptac e e.

In the construction shown at Figs. 5 and 6 the supply pipef is carried direct into the casing a and is closed at its end thus forming a water receptacle. It is formed with slits l in its under side through which the In all these forms the Water or other liquid enters the chamber a in a series of close jets or sheets and the exhaust gases are compelled to pass right through the liquid whereby they are purified.

The combined deodorizers and silencers shown at Figs. 7 to 11 are all shown with the water supply pipe f entering the chamber a and having slits Z, Z.

In Fig. 7 the case a has a number of vertical fiat metal screens m some of which are entirely'foraminated and others of which, m, are partly foraminated and partly solid, which not only act to silence the exhaust gases but also prevent the water being blown right through .the casing (1. These screens m, m, precipitate the Water and matter contained therein as hereinbefore described.

In Figs. 8 and 9 the combined deodorizer and silencer is not only provided with the flat foraminated screens m but it is also provided with baffles n, 0, which meet at an angle on the center line of the casing. These baffles occupy a little more than half the diameter of the casing a, or in other words they slightly overlap each other, so that the gases are compelled to pass in a zig-zag direction through the case a. The lower baffles o are perforated as shown to allow the water to pass along the bottom of the ease to the sump 71.. If desired both sets of baffles n, 0, may be formed with perforations or slits as shown to allow some of the gases to pass through the same.

In the combined deodorizer and silencer shown at Figs. 10 and 11, all the baffles n, 0, are arranged at one end of the apparatus and all the llat screens m are arranged at the other end of the apparatus. If desired the screens at maybe arranged at the inlet end of the apparatus and the baffles 17., 0, may be arranged at the outlet end of the apparatus, but this modification is not shown as it will be well understood.

Some of the baffles may be made partly of asbestos or other suitable fibrous material; one of such baiiies is shown in Fig. 10.
